Woodstove & Fireplace Air Supply
If your house is a typical tightly-built modern home, you need an Air Supply Ventilator (ASV). If you have a kitchen fan,
a bathroom fan, or a dryer vent, you need an ASV. If you have a fireplace, a woodstove, or vent-free gas, you need an ASV.
In short, all American homes would benefit from installing one or more ASVs.
Today architects, contractors, and intelligent homeowners realize that proper ventilation is a necessary component for personal
health and a healthy home. By bringing fresh filtered make-up air into your house from outside, the ASV ensures that your
fireplace or woodstove operates efficiently, with no smoke leakage.

Outside-In: How the ASV brings fresh air into your home
The ASV is made of tough ABS polymer. Outside air enters the ventilator through a louvered grill, which provides protection from rain. Insects and vermin are excluded by a separate screen located directly behind the grill.Air flows into your house through a tube inside the ASV that can be cut to fit any wall thickness up to 14 inches. A manually-operated damper controls the airflow, with settings ranging from fully closed to fully open, or any volume flow in between. If desired, you can dictate a constant minimum airflow by popping out an optional plug built into the damper.
Air passes through a filter before entering the room. The ASV’s filter captures dust and is removable for cleaning. The filter also helps block outside noise. If you suffer from asthma or seasonal allergies, optional filters are available that remove pollens and other very fine particulates from the air before it enters your home.
The ASV comes complete with hardware and caulking for installation. The standard dust filter comes installed in every new ASV. It can be washed as often as you like. Inexpensive, and allows maximum airflow. Filters ordinary dust particles exceeding 10 microns. The specialized pollen filter or high-tech filter may be ordered separately (see below).

You may also select an optional upgraded filter that best serves your needs:
Special pollen filterFilters out 90% of air pollutants over 5 microns in size. This filter should not be washed as its efficiency will be adversely affected. Unique design promotes longer filter life, even with heavy soiling. Filter affects volume of air replenished – recommended to keep air supply damper fully open to maximize airflow.
High-tech filterFilters out extremely small particles, ½-micron size and up: viruses, bacteria, asbestos particles, skin and hair particles, and unburned hydrocarbons from gasoline and diesel exhausts. Internal fibers are electrically charged to act as a magnet, and the filter’s high efficiency causes it to become soiled quickly. Not washable. Requires replacement at frequent intervals. Reduces airflow through ventilator – damper must be wide open when using.
